OIL-BURNER.

Specification of Letters Patent. Patented June 29, 1915 Application filed January 27, 1915. Serial No. 4,730.

To all whom it may concern Be it known that I, DAVID JORDAN, a citizen of the United States, residing at Sweetwater, in the county of Nolan and State of Texas, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to improvements in oil burners, more particularly to devices adapted to be inserted in stoves and ranges and employing kerosene oil as a fuel, and has for one of its objects to improve the construction and increase the efficiency and utility of a device of this character.

Another object ofthe invention is to provide a simply constructed device which may be applied to stoves and ranges of various parts may be readily renewed without discarding the remaining portions of the device.

Another object of the invention is to provide a simply constructeddevice, whereby may be controlled or With these and other objects in view, the invention consists in certain novel features of construction as hereinafter'shown and described andthen specifically pointed out in the claims; and in the drawmgs illus-' trative of the preferred embodiment of the invention Figure 1 1s a longitudinal sec-' tional view of the improved device located in the fire box of a conventional cook stove or range; Fig. 2 is a 'transverse'section on the line 2-2 of Fig. 1 Fig. 3 is a detached plan view of the burner "device; Fig. 4 is a view similar to Fig. 3 removable portion of the burner casing.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device may be applied without material structural change to the fire pot portions of ordinary stoves or ranges and comprises a central tubular member, indicated as a whole at 10, and inserted through the end walls 11 of the stove or range and above the grate 0f the stove, indicated conventionally at 12. The member 10 Fig. 2.

without the upper- -with a closure cap 13 and at the other end with a reducing coupling 14 into which the feed pipe for the hydrocarbon fuel, indicated conventionally at 15, is inserted. A needle valve, illustrated conventionally at 16, is connected into the feed pipe 15 to control the flow of liquid. The feed pipe 15 leads to a suitable reservoir, not shown, as the reservoir forms no part of the present invention.

The cap 13 and the reducing coupling 14: are interchangeable so that the feed pipe may be connected to the member 10 at either end.

The portion of the member 10 within the fire boX is provided with suitable orifices 17 for the escape of the liquid fuel. Surrounding the member 10 within the fire box of the stove, is an inner tubular casing 18 divided longitudinally, as indicated at 19, the division being located to register with the orifices 17, as illustrated in Fig. 2. The inner casing 18 is slightly larger than the burner tube 10, whereby an annular space is left between the members 10 and 18, as shown in The tubular member 10 and the inner casmg 18 are incased in an outer larger casing formed 1n two portlons 2021, each portlon being in the form of a half cylinder, thev lower portion 20 of the casing being preferably provided with shoulders 22 to receive the adjacent edges of the member 21, as illustrated in Fig. 2. The portion 20 of the outer casing is provided with semi-circular ends 23- 24 having half bearings to receive the member 10, while the upper portion 21 of the outer casing is provided with semi-circular ends 25-26, likewise having semi-circular bearings to engage over the member 10. Wound around the inner casing 18, is a coil of refractory material, such as asbestos, in the form of a flat rope and represented conventionally at 27. The asbestos is open and porous so that gas will freely pass through it.

The outer larger casing portion 21 is provided with suitable burner orifices 28 in its upper part for the escape of the gas. Bearing over the upper larger casing member 21, is a semi-circular shell or plate 29 engaged by its edges by ribs 30 upon the member 21. The member 29 is provided with a plurality of orifices 31 which register with the orifices 28 when the member 29 is disposed in one position, as illustrated in Fig. 1 and which will be disposed opposite the solid portion of the member 21 when the member 29 is moved into another position, and then when the'member 29 is disposed in 'an intermediate position, the orifices 283l may be partially closed to control the flow of gas. By this simple means, a combined cut off and controller device is produced of very simple construction. The member 29 is provided with a projection 32 to enable the member 29 to be adjusted relative to the member 21, and thus control or entirelycut off 'the How of the gas. The projection32 is accessible through one of the griddle holes of the stove, the griddles being represented conventionally at 33. Sheet metal disks 3% are preferably interposed between the asbestos member 27 and the ends of the outer casing members, and likewise between the ends of the inner casing 18 and the ends'of the outer casing members, as shown in Fig. 1.

The parts, including the asbestos member, are readily separablei'or renewal or repairs, so that the life of the device is materially increased, as the upper parts are subjected to the greater amount of the heat and will wear out more quickly than thelower portions. v

The improved device is simple in construction, can be adapted, without material structural change, to stoves, furnaces and the'like,'but is more particularly adapted to the fire pots of cooking stoves or ranges.

Having thus described the invention, what is claimed as new is:

1. A burner including a feed tube for the Y ,fuel having discharge orifices, a body of porous refractory material, a casing inclosing said body and formed in a plurality of separable members, one of said casing members having discharge orifices spaced apart and disposed in alinement longitudinally of the casing, and a movable memberengaging said orificed casing member and having vent orifices registering with the orifices of the casing member when in one position and registering with the imperforate portion of the adjacent casing member when in another position. I

2. A burner including a feed tube for the fuel 'and liaving-discharge orifices, an inner casing having a longitudinal opening and inclosing said feed tube, a body of porous refractory material inclosing said inner casing, and an outer casing inclosing said body and formed'oi' aplurality of separable members, one of said outer casing members having discharge orifices. V V

3. A burner including a feed tube'for the *fuel and having discha'rgeorifices, a body of-porous refractory material, an outer casing inclosing said body and formed of a plurality f separable members, one of said outer casing members having discharge oriiices, and a combined controlling and cut off member movable over said orificed outer casing member and having a plurality of discha-r e orifices re isterin with the orilices of the outer casing.

4.. In afiburner, a zteedtube having discharge orifices, "an outer casing inseparable parts and having ends engaging the feed tube, bearing disks carried by-the feed tube and engaging the outer casing ends, 'an inner casing having a longitudinal opening and inclosing said diced tube and bearing at the ends againstsaid;disks, and a body of porous; refractory material surrounding "the inner casing and bearing against the disks.

.5. A burner including a feed tube for the T1161 and having discharge orifices, -an -inner casing having a longitudinal opening and inclosing said iejed 'ti1;be,;an;ou-ter easing formed of a plurality ofseparablemembers, one ofthe outer-casing members having discharge orifices, and a member-o-f-porousrefracto'ry 'materia-l in rope like form and wound around the-inner casing member and spaced from-the outer casing member.

In -testimony whereof I affix my signature in'ipresenee of two witnesses.
